call two class in code example
Example 1: css assign multiple classes to one element
To specify multiple classes, separate the class names with a space,
e.g. <span class="classA classB">.
This allows you to combine several CSS classes for one HTML element.
Example 2: more than one class in div
<!-- You can use multiple classes per element if you simply put spaces between the names: -->
<div class="c1 c2"> This div has two classes </div>
